SAMUEL L. P. GARRETT, OF LEWISBURG, TENNESSEE.

, RAILROAD-GATE.

SPECIFICATION forming part of Letters Patent No. 226,299, dated April 6,1880.

Application filed September 5, 1879. I

To all whom it may concern Be it known that I, SAMUEL LOGAN PLEAS- ENTGARRETT, of Lewisburg, in the county of Marshall and State of Tennessee,have invented a new and Improved Railroad-Gate, of which the followingis a specification.

Figure 1 is a plan view of the operative mechanism of the gate. Fig. 2is a front elevation of the gate, with the box inclosing the mechanismpartly broken away to exhibit the same. Fig. 3 is a side elevation ofsome parts of the mechanism.

Similar letters of reference indicate correspondin g parts.

The object of this invention is to provide a railroad-gate that anapproaching train will open by the pressure of the flanges of the wheelsupon a horizontal bar fixed parallel with the rails and rising a littleabove them.

The invention consists in the combination, with railroad-gates, oflazy-tong levers operated by the wheels of cars in such a way that whenthe wheel depresses levers the lazy-tongs spread and throw open thegates, thelatter being so arranged as to close by their own gravity, allas hereinafter described.

In the drawings, A A represent the gateposts, carrying on their facesthe sheaves B B. G G are the gate-sections, provided with longitudinalslots D D, in which the sheaves B B engage. E E are the railroad-rails.F is the bar set on the upper ends of the vertical bars G G, andextended on each side of the gates, and so placed as to receive thepressure of the flanges of the car-wheels as they pass over the rails EE. This bar G is jointed at a, and is flexibly connected at a to an armon the rocking shaft B, that is journaled in the cleats I I. At thecenter of the shaft H, and to an arm thereon, is jointed the bar K,whose other end is attached to side prolongations of the compound leveror lazy-tongs L, which is centrally pivoted at m on a fixed standard orbase beneath it. The other ends of the lazyton gs L connect at 3/ withthe upward-curved rods M M, that carry within their loops b b thesheaves N N, and whose upward-projectingends are fastened to the lowerand outer corners of the gate-sections O G.

In order to avoid friction and for the proper support of these curvedrods M M, the rails O O are provided for the sheaves N N to rest and runupon.

When the gate is closed the flanges of the cai wheels running on thetrack will press upon the bar F, which, in turn, will bear down upon thebars G G and cause them to turn the shaft H inward, so that the bars Kshall quickly force outward the end of the lazytongs L and the curvedrods M M, that are fastened to the gate-sections O 0. Thus the gate isinstantly opened, the sections 0 G being drawn apart, and is so retainedby the pressure of the wheels upon the bar F until the train has passed,when their own weight (the weight of the sections 0 O) and their in wardinclination cause them to close again. If the bar F be placed outside ofthe rail E it must be set higher, so that the overhanging tread of thewheels may press upon it.

All the levers and bars may readily be boxed in for protection fromsnow, so that they will be in condition to operate at any time.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The gate-posts A A, sheaves B B, gateseotions O O,provided with slots D D, bar F, bars G G K K, lazy-tongs L, rockingshafts H H, curved rods M M, sheaves N N, and rails O O, constructed andarranged substantially as herein shown, and for the purpose described.

2. The combination of the lever or lazytongs L with rods M M and sheavesN N, substantially as herein shown and described.
